您可以使用标记来显示地图上的单个位置。此页面介绍了如何以程序化方式和使用 HTML 来向地图添加标记。
使用 HTML 添加标记
如需使用 HTML 添加 3D 标记,请在 gmp-map-3d 元素中添加一个 gmp-marker-3d 子元素。下面的代码段显示了如何向网页添加标记:
<html>
<head>
<title>3D Marker HTML</title>
<link rel="stylesheet" type="text/css" href="./style.css" />
<script
async
src="https://maps.googleapis.com/maps/api/js?loading=async&key=AIzaSyA6myHzS10YXdcazAFalmXvDkrYCp5cLc8&libraries=maps3d"></script>
</head>
<body>
<gmp-map-3d
center="40.7489,-73.9680,0"
heading="315"
tilt="65"
range="800"
mode="SATELLITE">
<gmp-marker position="40.7489,-73.9680" title="UN Headquarters">
<div class="custom-marker">
United Nations Secretariat Building
</div>
</gmp-marker>
</gmp-map-3d>
</body>
</html>以程序化方式添加标记
如需以程序化方式向地图添加 3D 标记,请创建一个新的 Marker3DElement,并向其传递 lat/lng 坐标以及对基本地图的引用,如以下示例所示:
async function init() { // Make sure the Marker3DElement is included. const { Map3DElement, Marker3DElement } = await google.maps.importLibrary('maps3d'); const map = new Map3DElement({ center: { lat: 37.4239163, lng: -122.0947209, altitude: 0 }, tilt: 67.5, range: 1000, mode: 'SATELLITE', gestureHandling: 'COOPERATIVE', }); const marker = new Marker3DElement({ position: { lat: 37.4239163, lng: -122.0947209, altitude: 50 }, // (Required) Marker must have a lat / lng, but doesn't need an altitude. altitudeMode: 'ABSOLUTE', // (Optional) Treated as CLAMP_TO_GROUND if omitted. extruded: true, // (Optional) Draws line from ground to the bottom of the marker. label: 'Basic Marker', // (Optional) Add a label to the marker. }); map.append(marker); // The marker must be appended to the map. document.body.append(map); } void init();
